[mythtv-users] OT: Adding second drive using LVM on /

[Michael Starks]

I have an LVM VG partitioned as follows:

/boot
/swap
/tmp
/var

All of my Myth files are on the root partition and it is quickly filling
up.  I have extended the volume group successfully, but I'm having
problems resizing the file system.  I know that it needs to be unmounted
in order to user resize2fs (incidentally, is this OK for ext3?).  I have
unmounted it by booting into Linux rescue mode (RH 9.0) but when I run:
resizefs /dev/pvname/lvname is tells me it's not a valid device (or
thereabouts).  In retrospect, it would have been easier not to put my
media files on the root partition. Can I extend this file system the way
I have it set up now without some type of destructive command?  Thanks.
